Removed the Packing program. Please use the Data Folder method for mod usage for now until a public release of the 1.05/Plus mod loader.
You can activate Data Folder mode by using this tool to unpack Mania's Data.rsdk and then renaming Data.rsdk using anything else. This will make the game run from the new Data folder and you can put mods in there.
For those who say this is a lie, here's something you should know. The .EXE file isn't the only thing you should replace here, you should also replace the .txt files. This is what the program reads to see what files it should extract from the rsdk file. When the unmodified .txt files are read, it only extracts the non-plus content, and here's where the new files come into play. Hope this helps, because from my experience this is no fraud.
